MACHINE FOR ROLLING METAL.

Application filed March 26, 1921. Serial No. 455,828.

To all whom it may concern: I

Be it known that 1, Max Knox, a citizen of the United States of America, and a resident of Crescent Springs, in the county of Kenton and State of Kentucky, have invented a new and useful Improvement in a Machine for Rolling Metal, of which the following is a specification.

An object of mill to roll metals such as gold, etc., into very fine sheets, in which the axis of the shafts will be 4 arallel at all times and in which there wi be no lost motion between the driving means and the rolls.

Another object is to provide a device for the purposes stated that is capable of very fine adjustment. 4

Another object is to provide a device'for the purposes stated that will roll the metal into smooth sheets devoid of waves, ridges, or humps. 7

Another object is to provide a device of the type referred to that is simple in construction and operation.

These and other objects are attained. by the means described herein and disclosed in the accompanying drawing in which:

Fi 1 is a side elevation of a device embodylng my invention, parts being broken away.

Fig. 2 is a sectlonal view on line 2-2 of Tig. 3 is a sectional view on line 3-3 of ly invention comprises a frame or housin A upon which are'mounted the adjustab e bearing blocks 6 and b supporting the rolls D and D adapted to be revolubly actuated and between which. themetal to be rolled is passed. The rolls are; adapted to be adjusted in relation to one another by means of a hand lever and a'cam F'a'cting upon the bearing bloc b and 6.. a I

The housing or frame A'has a, base a from which extend theslotted uprightsor sides a and a. The slots a inthe sides are preferably vertical and are parallel with one another. The top on connects the upper ends of the sides a and a. The housing has a way at extending therethru from the front a to the rear a The slots a register with the way a A transverse bore a is formed in the top or head a ofthe housing, and within this bore is rotatively mounted a crank shaft a A hand crank a is mounted on the crank shaft a. A bevel gear a is my invention is to provide a.

mounted on the shaft a". A transverse bore a is formed in the base and communicates with the lowerends of the slots (1 in the sides. The bore also communicates with the way a). 1

Slidably mounted in the slots-a. in the sides of the housing are the upper bearing blocks b and the lower bearing blocks '1) between WhlCh are disposed the springs 6 The upper blocks 6 are retained at the upper end of the slots a by the action. of the springs 6 Y The upper revoluble' shaft 0 is mounted upon the upper blocks b, and the lower rev- 0 uble sha t 0" is --mounted in the lower blocks 6'. An upper roller D and a lower roller D are mounted upon the shafts c and 0 respectively and are disposed inthe way a intermediate the sides a and a of the frame The shafts c and c extend thru the bearing blocks b and b in the slot in the s1de a of the frame. The worm wheels d and d' are mounted upon the shafts c and 0' respect vely and engage the worms e and e respectlvel'y mounted on theshaft 6 supported upon the exterior of the side a by any suitable means such as the brackets e. The i drive shaft e has mounted upon its upper end a bevel gear 6* engaging the bevel gear a". The wormse and e are right and left handworms adapted when revolved, to actuate the worm wheels in opposite directions. A cam shaft F is rotatably mounted in the transverse bore'a and has formed on it the cams f and f which lie in the bore a immediately below the slot 01 On each cam is formed a cam face f adapted to be moved past the slots a and to engage the lower ends of thelower blocks 6 Adownwardly projecting lug 7" extends from the cam F. A threa ed hand crank g is adjustably mounted in a threaded way a formed on the forward wall of the/base a of the housing A and engages the lug f on the cam. The shafts '0 and 0 aremounted on the frame in parallelism. The operation of my device is as follows: Rotatory motion is transmitted to, the rollers D and D by means of the crank a", crank shaft 01", bevel gears (1 and c, drive shaft 6, worms 6 and c worm wheels d and 05 and the shafts c and 0. Because the worms are right and left hand, the rollers will be actu ted in opposite directions whereby the rolls will feed a strip of metal between themselves as they .roll the metal. The

rollers are adjustable in relation to one another ,by' means of the hand crank g. When the hand crank is actuated so asto revolve the cam F, as shown in Fig. 1, in a counterclock-wise direction, the cam faces f? move the lower blocks 6 upward into the slots a and against the springs 6 thereby bringing the rollers into closer relation.

When the cam F is actuated in a clock-wise direction, the springs I)? retain the blocks 6 upon the cam face f and the blocks separate Wherefor the rollers are moved apart. The worms and worm wheels permit ready adjustment of the rolls without the development of lost motion between the rolls, wherefor the metal will be rolled into uniform sheets devoid of waves or ridges.

If desired the springs Z2 may be dispensed with and the blocks 6 be fixedly retained upon the frame at the upper endof the slots M. A. sprin a is then mounted upon the base of the frame and on the cam F. The spring yieldingly retains the lug f in engagement with the crank When the crank g is moved out of the threaded waya", the

verse bore, blocks mounted slidably in the slots, cooperating rolls mounted upon the blocks and disposed intermediate the sides, means yieldably spacing the blocks, a cam shaft revolubly mounted in the transverse bore, cams on the cam shaft engaging the blocks and adapted to adjustably move the blocks against the yieldable spacing means, and means to impart rotatory motion to the rolls.
